Provision of a timepiece in which it is possible to improve the weathering performance of a stopper means preventing inadvertent rotation or a rotated body accommodated in a case and idling of an operation member rotating a rotated body while, for example, the timepiece is being carried about and in which there is involved no increase in the diameter of the head portion of the operation member. Mounted to a case to which a pipe is fixed is an operation member having a head portion rotated outside the case and a shaft portion inserted into the pipe so as to be movable between a first position and a second position. The operation member is urged by an urging member (coil spring) such that the operation member is arranged at the second position. Inside the case, mounted to the shaft portion is a drive gear constantly in mesh with a driven gear portion of a rotated body (display body) accommodated in the case. A stopper means S is provided inside the case. In the state in which the operation member is arranged at the first position, the stopper means S prevents rotation of the head portion, and, in the state in which the operation member is arranged at the second position, the stopper means S allows rotation of the head portion for conjunction-moving the rotated body.
